Sad to say, this probably won't work. There have been several petitions that have thousands of name on, both on the net and in stores and they have not made a difference with corporate Wal-Mart.
I stopped buying most of my fabrics there a couple years ago and started buying from sales online and the sale section of my LQS. The quality is better with comparable pricing.
Good luck to all that need their Wal-Mart fabric department getting them to understand.
